Thread: [Ogoglio-developers] Sketchup (1) - Avatars (2) - Spatial sound (3)

Hi!

I would like to ask 3 questions:

- I have started to make models with the very user-friendly Google Sketchup -- do you have any best practices or recommendations for importing Google Sketchup models (exported in OBJ format) into Ogoglio ?

- The set of Ogoglio avatars is pretty limited today -- I'd like to create more of them-- do you have guidelines/tricks/sources for us making additional ones ?

- "Spatial sound": what's the best way to get "spatial sound" in an Ogoglio space/world, ie sound whose volume depends on distance from sources (I guess one would need to javascript something or so) ?

Thanks in advance !

These are all good questions.  I'll try to take a stab at it, although 
Trevor has been doing most of the avatar-related stuff on Transmutable.

1) I believe we can handle pretty much anything in OBJ format, provided 
it stays under our limit in terms of total file size.  I believe that 
the system currently imposes a 1 megabyte limit on OBJ files.  Once you 
get your avatar model done (see #2) then we should talk about how to 
insure that your server exports them properly so that web browsers will 
see them.  There is also some work to do if you would like to have the 
animations (which are BVH form) work properly with your avatar.  I'd say 
first get the modeling done (the hard part!) and then the rest you can 
copy from our examples.

2)   Ogoglio will be getting some new avatars in the next couple of 
weeks.  Early pictures of "joe" the male avatar are already available:

http://blog.transmutable.com/2008/01/hey-joe.html

These will be CC licensed, so it should not be too onerous to use.

3) We currently have no "built-in" story for how to do sound in a 
space.  This has to be done by other web-based means at the moment.  We 
have experimented successfully with getting audio streams played into a 
space, but this is not generally available.  If you have ideas of 
web-based systems that can support this type of functionality, please 
let us know.

hope this helps
ian

Ian's on the mark but I'd like to add a couple of notes.

You can make the total scene size larger than 1MB by breaking it up
into pieces, each of which are less than 1MB.  You want to do this
anyway because scenes are progressively loaded so you want smaller
chunks so that your users can start walking around a space as soon as
the first chunk is loaded.

If you generate obj from Sketchup that doesn't load, send it my way
and I'll take a look.  The obj loader supports a fair number of quirks
that appear in that format, but editors are always coming up with new
ways to break the spec.

If you're the type of excellent person who values the Ogoglio project
and wants to contribute back in the form of Creative Commons or Apache
2 licensed models or textures, we're always looking to make the
default experience as smooth and beautiful as possible.  Transmutable
is footing the bill for new avatars by professional modelers, but once
the're in place it would be good if they had somewhere gorgeous to
hang out.

You can look at example avatars in the ogoglio-bodies package of the
source repository (which you can browse via the web at the sourceforge
project) to get an idea of how the avatars work.  One way to get
started might be to mutate Joe or Mike before you start from scratch.
